Using Octave or MATLAB;

Given, the mass of John is 100 kg, the mass of the chute alone is 5kg. Assuming the body area of John Kruger to be 1 m² and the area of the closed chute to be 0.5 m². Now assume that the airplane is at 5000 m. The parachute has an area of 0.5 m^2 and leaves the airplane 45 seconds before John. Plot both the parachute (red) falling and John falling head down with an area of 0.3 m^2 (blue) on the same plot. Plot the position graph above the velocity graph.
